Ruined 8th-century Benedictine abbey in Glastonbury, Somerset, England. 

Glastonbury Abbey was once the largest Benedictine monastery in England, St. Mary's.
The abbey was a holy place for pilgrimage.
During the time of Henry VIII it was destroyed and became a ruin.
Some claim that Glastonbury Abbey existed during the lifetime of Jesus Christ.
There is a legend that Jesus Christ visited this place as a youth with his uncle Joseph of Arimathea.
One of the British historians, Gildas, who probably lived in the 5th or 6th century, said that Jesus visited Glastonbury for the purpose of meditation, and this was in the last years of the reign of Emperor Tiberius, that is, around 27 AD.
The book of the poet Robert de Boron “Joseph of Arimathea” talks about the city with the Holy Grail - the cup from which Jesus drank during the Last Supper and into which Joseph collected his blood after the crucifixion. The risen Christ commanded that Joseph or his descendants take the cup to the heavenly lands of Avalon, now identified with Glastonbury Abbey in England.
They say that the Grail was brought here by Joseph of Arimathea himself.
The search for the Holy Grail became one of the main legends of the Arthurian cycle.
